722.38 is what percent of 1520 - step by step solution

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 1520 is 100% - because it's the output value of the task.
2. We assume, that x is the value we are looking for.
3. If 100% equals 1520, so we can write it down as 100%=1520.
4. We know, that x% equals 722.38 of the output value, so we can write it down as x%=722.38.
5. Now we have two simple equations:
1) 100%=1520
2) x%=722.38
where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:
100%/x%=1520/722.38
6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 722.38 is what percent of 1520

100%/x%=1520/722.38
(100/x)*x=(1520/722.38)*x       - we multiply both sides of the equation by x
100=2.1041557075224*x       - we divide both sides of the equation by (2.1041557075224) to get x
100/2.1041557075224=x
47.525=x
x=47.525

now we have:
722.38 is 47.525% of 1520
